Definitions
- the present invention relates to a fixing member used for fixing a member supporting a solar cell module to a roof material when the solar cell module is installed on a roof.
- the size of the solar cell module and the pitch of the roofing material are limited because there are restrictions on the position of the roofing material such as slate.
- the position where the fixing member should be attached overlaps with the position where the fixing member cannot be attached, and the fixing member cannot be attached.
- the fixing member 200 attached to the roof material is provided with a groove 202 into which the bolt head portion 203A can be inserted, and a through hole 211 through which the bolt shaft portion 203B is inserted.
- the holding tool 210 which has has the latching
- the fixing member 200 When fixing the solar cell panel to the roof, the fixing member 200 is attached to the roofing material, the bolt head portion 203A is slid in the groove 202, and then the bolt shaft portion 203B is inserted into the through hole 211.
- the presser 210 in a state where the engaging portion 215 is engaged with a slide groove (not shown) formed on the periphery of the solar cell panel is fastened from above and below by nuts 122 and 218. As a result, the solar cell panel is pressed from above by the presser 210, supported by the fixing member 200 via the bolt 203, and further fixed to the roof material via the fixing member 200.
- the above-described fixing member 200 requires that the solar cell panel side has a specific structure corresponding to the structure of the fixing member. That is, in the fixing member 200, the slide groove that engages with the locking portion 215 needs to be formed on the periphery of the solar cell panel. Therefore, there has been a demand for a fixing member that can be used for general solar cell modules without requiring a specific structure on the solar cell module side.
- the bolt shaft portion is limited to limit the range in which the bolt 203 can slide.
- a cover member 220 having a hole 221 inserted through 203B is attached so as to cover the upper surface of the fixing member 200. Therefore, there are problems that the number of parts is large, the installation work is complicated, and the cost is increased.
- the present invention can fix the solar cell module to an appropriate position of the roofing material, and can be used for general solar cell modules in general and few. It is an object to provide a fixing member having a number of parts.
- the fixing member according to the present invention is a position higher than the base portion by a flat base portion attached to the roofing material and a pair of top plate support portions erected on the base portion.
- a flat plate-shaped top plate portion supported by the plate, a long hole portion penetrating the top plate portion and closed at both ends, a shaft portion having a size passing through the long hole portion, and the long hole A head portion of a size that does not pass through the portion, and the shaft portion is inserted through the elongated hole portion with the head portion positioned below the top plate portion, and a support member for the solar cell module.
- the head insertion hole that communicates with the central axis of the elongated hole portion is positioned on a line projected on the base portion.

- the support member can be fixed to the roof material via the fixing member, and thus the solar cell module supported by the support member can be fixed to the roof material.
- the bolt can be slid along the long hole portion, the base portion and the support member can be relatively slid. In other words, the base portion and the support member can be separated and approached by the length of the long hole portion.
- the fixing member can be attached to the roofing material by a fastening member such as a nail or a screw nail inserted therethrough.
- the fixing hole is “located on a virtual line obtained by projecting the central axis of the long hole onto the base part”, that is, the fixing hole is on a virtual line directly below the central axis of the long hole. Therefore, the fixing member is fastened to the roof material on the same axis as the portion that receives the load supported by the supporting member via the bolt. Therefore, the solar cell module can be stably fixed to the roof material via the fixing member.
- the fixing hole is adjusted so as to be positioned on a structural material such as a rafter, the fixing member is stably supported by the structural material, and the solar cell module roof material via the fixing member and the supporting member.
- the installation strength can be increased, which is preferable.
- both ends of the long hole portion are closed ends, even if the bolt is loosened, the bolt will naturally stop at the eave side end portion of the long hole portion. That is, the range in which the bolt slides is limited without separately providing a member such as the cover member of Patent Document 1 described above.
- the head of the bolt does not pass through the long hole, but the head insertion hole large enough to pass the head is connected to the long hole. It can be located below a top plate part via.
- the fixing member of the present invention does not require the solar cell module side to have a specific structure, it can be used for general solar cell modules.
- the specific structure for supporting the solar cell module is not limited, so the solar cell module is fixed to the roofing material using various types of support members. can do.
- the fixing member according to the present invention may be configured such that “the pair of top plate support portions are erected from the base portion at positions apart from the pair of sides of the base portion, respectively.
- the fixing member in addition to fastening the fixing member to the roof material by the fastening member inserted through the fixing hole portion, the fixing member is also fastened to the roof material by the fastening member inserted through the “auxiliary fixing hole portion”. be able to. Therefore, the fixing member can be more firmly fixed to the roofing material, and as a result, the installation strength of the solar cell module on the roofing material can be increased.
